To all whom ztmayooncern:

-Be it known that I, GEORGE M. PETTEN- GILL, residing at Haverhill, in the county of Essex and State of Massachusetts, have invented an Improvement in Top-Lift-Cementing Means for Heel-Nailing Machines, of which the following is a specification.

This invention relates to certain improvements in heel nailing machines which are adapted to cement the top-lift automatically whileheld in the top-lift holder of the machine, and more particularly, it relatesto means for performingthis function which are especially adaptedto be applied to a heel nailing machine of the vertically reciprocating cross-head and turrettype, such as is shown in my pending application Serial No. 526,561.

The object of my invention is to provide a simple device of the above described character which will be efi'ective in operation, and willbe inexpensive to manufacture and unlikely, to get out of order.

In the drawing, Figure 1 is a front elevation of the head portion ofa. heel-nailing machine provided with my invention, and showing the parts in one position. Fig. 2 is a detail view showing the parts in a different position. vFigs. 3, 4 and 5 are enlarged detail views of the cement-applying device. Fig. 6 is a detail view of the top-lift holder.

In the drawing a indicates the mainframe in which the carrier, or cross-head b is mountedto reciprocate vertically, said crosshead having a turret 0 rotatably mounted thereon, andsaid turret being provided with a driver arm cl. and a spanker and top-lift holder arm 0.

The arm 6 has a top-lift holder mounted at its end which comprises a pair of adjustable jaws. f, having converging edges'for engaging the back edge "of the top-lift, and a spring-actuated clamping bar 9 for engaging the breast edge. Instead of having the spanker arm 6 arranged either at 180. or 90 from the driver arm cl, as has been customary, I arrange the same at an oblique angle thereto, so that the angle included between said arms (Z and e is approximately so that when the top-lift, a: is in position on the spankenplate, while the turret is in driving position, the lift will be heldinan .oblique position with relation, to the vertical with its flesh or inner side fa'cing'downward.

The locking bolt 9 acts to hold the turret in either of its two positions. 7 f As a matter. of convenience, a top -,lift

tray h is secured to the inner side of the frame a beneath the cross-head, and said tray is provided at'its front side with a depending lug it, toi'which a'horizontallydisposed arm 75 is pivotally connected, said arm the end thereof, at right angles thereto. A

having a standard adjustably mounted in V cement holder or receptacle I: is mounted on the upper end ofsaid standard j and a felt. covered roll m is rotatably mounted in the sides thereof, so thatthelower portion of I the roll will be. rotated inthe cement contained by the. receptacle, and the upper portion .wrll'projec't above the sides of the recepta'cle. The shaft of said roll is provided with a series of ratchet-teeth g, and a spring pawl p is mounted on the holder is in position to engage said teeth and prevent rotation of said roll to the right while permitting free rotationto the left. A bolt'n is connectedto the tray and passes through the arm 71, and a spring 0 is inclosed between ahead on the lower end of said bolt and the under side of thearm a, said spring acting to hold said arm 71 in an approximately horizontal position.

7 A stop screw 8 is mounted on the clamping bar 9 at the lift-engaging side thereof, and extends parallel thereto in position to enga'gethe lower side edge of a top-lift held sis in the ho1der,when the holder is in its initial ,1.

position shown in Figs. 1 pose to be described.

and 2, for the pur- Theoperation of theabovedescribed device is as follows :A top-lift w, -having been placed in the top-lift holder, as shown in-Fig. 6, while the turret is locked in nailing position, in which the top-lift holder is held in its initial position, and the screw 8 having been adjusted so that its end. bears against the lowermost edge of the lift, when the cross-head descends to perform the nail- -driving operation, the top-lift will be carried vertically downward in the oblique positionin which it is held, and, duringthe latter portion of this movement, into engagement with the roll m,-the surface of which will be covered with cement. The roll will be engaged by the top-lift at a point on the latter a short distance from its lowermost edge, and, on further downward movement of t e flo -head, the c ment g- 011 W 1 e too its

rolled across the surface of the lift, and when thecross-head reaches the limit of its "downward stroke the lift will have moved in serve the purpose, the construction shown being preferable, I believe, to any of which On the return, or upward movement of the cross-head, the cementing roll would be rotated in the opposite direction, but for the pawl 10, which engages the ratchet 1] thereon, and prevents such rearward rotation, so that,ras the toplift is carried upward, the roll will drag 011 the surface of the lift until the lift is carried out of engagement therewith, the spring 0 lifting the arm 2' to its normal position. As there is some frictional engagement between the top-lift and the cementing-roll on this return movement, the roll has a tendency to pull the top-lift out of the holder, and to prevent such occurrence the stop-screw s is provided, which bears against the lower edge of the lift and prevents such an occurrence. It will be observed that the cementing-roll is thus caused to rotate forwardly on each reciprocation of the cross head and thus to rotate in the cement contained in the receptacle is, so that a freshly coated surface of cement is presented to the top-lift on each cementing operation.

WVhile I prefer to have the spanker arm 8 held. at approximately 45 from the driver arm (Z, so that the swing of the turret will be as short as possible, and yet the spanker arm will not be so close to the operator as to interfere with the heel attaching operation, it will be obvious, that, so far as the cementing operation per 86 is concerned, itmay be performed more or less satisfactorily with the spanker arm held at various other angles between a horizontal and a vertical position, the limits of variation from the middle position shown being defined by practical con siderations.

I claim V r 1.
